SPECIFICATION forming part of Letters Patent No. 566,666, dated August25, 1896.

Application filed February 26, 1896. Serial No. 580,770. (No model.)

To aZZ whom it may concern:

Be it known that I, HARTW'ELL A. CROSBY, of Calais, in the county ofWashington and State of Maine, have invented a new and ImprovedLamp-Burner, of which the following is a full, clear, and exactdescription.

This invention relates to certain improvements in lamp-burners, and hasfor its object to provide a burner of a simple and inexpensivecharacter, having means for trimming the lamp-wick and extinguishing theflame operated by the movement of the wick-raising device, whereby thelamp-wick may be conveniently trimmed and the flame extinguished bymerely actuating said device to lower the wick.

The invention consists in a burner having a wick-tube and a wick-raisingdevice comprising a shaft mounted to turn and a spurwheel or disk on theshaft to engage the wick, and a trimming-plate pivotally mounted andarranged to play edgewise across the open end of the wick-tube andarranged to be engaged by said spur wheel or disk when the lampwick islowered, whereby said trimming-plate will be caused to pass edgewiseacross the mouth of the wick-tube to trim the wick by removing the crustor charred portion therefrom.

The invention also contemplates certain novel features of theconstruction, combination, and arrangement of the various parts of theimproved device, whereby certain important advantages are attained andthe device is made simpler, cheaper, and otherwise better adapted andmore convenient for use than various other similar devices heretoforeemployed, all as will be hereinafter fully set forth.

The novel features of the invention will be carefully defined in theclaims.

Reference is to be had to the accompanying drawings, forming apart ofthis specification, in which similar characters of reference indicatecorresponding parts in all the views.

Figure 1 is a sectional view taken vertically through a burnerconstructed in accordance with my invention. Fig. 2 is a sectional viewsimilar to Fig. 1, but taken in a plane at right angles to the plane ofthe section in Fig. 1; and Fig. 3 is a fragmentary perspective viewshowing the wick-tube and the trimmer and extinguisher mounted thereon.

In the views, 1 indicates the shell of the burner, having a threadedlowerportion 2, arranged to screw in the socket of the lamp in theordinary way, said shell being provided with upwardly-extending arms 3,supporting at their upper ends the air-distributer 4, at the edges ofwhich is formed a chimney-gallery 5 in the usual way. On theair-distributer is pivoted a cone or deflector 4, of ordinaryconstruction. The body or shell of the burner is provided with avertical wick-tube 6, adapted to receive the wick and provided in onewall with apertures 7 for the passage of the spur wheels or disks 8 ofthe wickraising device, these disks or wheels being secured on a shaftor stem 9, mounted to turn in the shell 1, as will be readilyunderstood.

The upper end of the wick-tube is beveled 0d slightly, as clearly seenin Fig. 1, and said upper end is adapted to be closed by thewicktrimming plate, which is of a width adapted to fit over said upperend of the wick-tube, and said plate 12 has downwardly-extendin g arms11 at its opposite ends, these being by preference formed integrallywith the plate 12, and being pivoted, as indicated at 10, to theopposite end walls of the wick-tube 6, as clearly shown in the drawings.The arms 11, which carry the trimming-plate 12, have their lower endsarranged to extend below the pivots 10, and said lower ends are tiedtogether by means of a cross plate 13, extending across one side of thewick-tube 6, in front of the openings 7 therein, through which the spurwheels or disks 8 extend. The cross-piece or tie 13 is also bypreference formed integrally with the lower ends of the arms 11, asshown in the drawings, and said cross-piece or tie is so located as tobe in position to be engaged by the teeth of the spur wheels or disks 8of the wick-raising device, as clearly shown in the drawings.

In operation, when the stem or shaft 9 is turned so as to raise the wickcontained in the wick-tube, the teeth of the disks or wheels 8 willengage the cross-piece or tie 13 and move the same away from the wall ofthe wick-tube 6, whereby the arms 11 will be swung pivotally and thetrimming-plate 12 will be caused to move from over theupper end of thewick-tube, as indicated in dotted lines in Fig. 1, this movement of thetrimming-plate permitting the upper end of the wick to pass upwardwithout being engaged by said trimming-plate, so that said upper end maybe readily ignited.

When the stem or shaft 9 of the wick-raising device is moved in theopposite direction to lower the wick, it will be seen that the upper endof the wick on passing down into the wick-tube will be withdrawn fromengagement with the trimming-plate 12, so as to permit said plate to bemoved over the upper end of the wick-tube to the position shown inFig. 1. The pivot-points 10 of the arms 11 whereon the trimming-plate 12is carried are so arranged that the lower ends of said arms are heavierthan the upper ends, whereon the plate 12 is carried, so that when thewick is withdrawn into the wick-tube said arms Will swing pivotally in adirection to move the plate 12 over the upper end of the wick-tube.

When the arms 11 swing pivotall y, as above described, the cross-pieceor tie 13 will be moved toward the side walls of the wick-tube 6, intoposition to be engaged by the teeth of the wheels or disks 8 of thewick-raising device, whereby said tie or cross-piece will be positivelyactuated, and the trimming-plate 12 will be caused to pass edgewise overthe charred upper end of the Wick to remove the crust therefrom, and toextinguish the wick,

so as to prevent the same from smoking.

From the above description it will be seen that the device is of anextremely simple and inexpensive nature, and is especially well adaptedfor the purposes for which it is designed, and it will also be obviousthat the invention is susceptible of some modification without materialdeparture from its principles or spirit, and for this reason I do notwish to be understood as limiting myself to the exact form andarrangement of the parts herein set forth.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. In a burner, the combination of a shell, awick-tube therein, a wick-raising device comprising spur-wheels arrangedto engage the wick, a pivoted arm, and a trimmingplate connected to thearm and arranged to pass edgewise across the upper end of the wick-tube,said arm being arranged to be engaged by the teeth of the spur-wheel, toswing the arm pivotally to move the plate across the end of thewick-tube, substantially as set forth.

2. In a lamp-burner, the combination of a shell, a wick-tube, awick-raising device comprising a spur-wheel to engage the wick, an armpivoted adjacent; to the wick and having its lower end weighted andarranged to be en gaged by the teeth of the spur-wheel of thewick-raising device, and a trimming-plate carried on the upper end ofthe arm and arranged to pass edgewise across the upper end of thewick-tube, substantially as set forth.

3. In a burner, the combination of a shell, a wick-tube, a wick-raisingdevice comprising a spur-Wheel to engage the wick, arms pivoted at theircentral portions at the end walls of the Wick-tube, and having theirlower ends weighted, a tie connecting the lower ends of the arms, saidtie being arranged to be engaged and moved by the teeth of thespur-wheels to swing the arms pivotally, and a trimming-plate carried onthe upper ends of the arms and arranged when the arms are swungpivotally to pass across the upper end of the wick-tube, substantiallyas set forth.
